    What do these markings represent? I have quantity 3, four speed ceiling fan pull switches all with leads marked l, 1, 2, 3. They are all electrically different inside. Lowes and HD both sell one fan switch. However, since they are all different inside, one does not work in all fans, dispite the same wire markings. Im confused.

    Start by hooking up 12 or 24 VAC to different pairs of motor wires and see if you get different speeds.

    Run some ohm meter test on all 6 possible hookup variations.

    Get back with us.

    why? The fan does have 4 speeds(incl off). The pull chain broke. I can still move the switch thru all four positions, resulting in fan off, slow, med, fast. I need to replace the switch.

    switch removed from fan:
    L black
    1 yellow
    2 pink
    3 gray
    position one = no continuity
    position two = black & yellow continuity
    position thee = black & gray & pink continuity
    position four = black & gray continuity

    fan switch bought:
    L white
    1 yellow
    2 yellow
    3 black
    position one = no continuity
    position two= L & 2 continuity
    position three = L & 1 continuity
    position four = L & 1 & 2 continuity

    3rd Switch removed from broken fan:
    L black
    1 purple
    2 brown
    3 gray
    position one = no continuity
    position two= L & 1 continuity
    position three = L & 2 continuity
    position four = L & 3 continuity

    This one:
    does not make sense. You show 1 as yellow, and 2 as yellow - same colors? And you list 3 black, but don't show it being used anywhere.

    more important is that I need a switch that operates like the one removed from the fan that I'm trying to fix.
    position one = no continuity
    position two = black & yellow continuity
    position thee = black & gray & pink continuity
    position four = black & gray continuity

    With the switch removed and the fan suspended I did touch the fan black and yellow and got a slow speed, black & gray & pink gets med speed, black & gray gets fast speed. So, its off, slow, med, fast, off slow, med, fast, off...

    Well, it seems like the one you just posted would work - but you would have low, then high, then medium.
